only once when I was about 17.
Is that in answer to my question Have you ever had any kind of situation where you got to know a man really quite well that lead to any kind of physical attraction (for example a boss or colleague at work or a friend at university/in education)?
or in answer to @JenniferJareau
If it's to my question and you became later attracted to someone you knew well (ie. you had a physical attraction that was not evident to you for a long time until you knew them very well), this may possibly be an indicator of demisexuality but it's hard to know.
It's partly circumstance dependent as to whether someone who is demisexual realises they are consider these scenarios -
Woman is demisexual. At school she has a serious bf she's attracted to as he was her best friend. They split up at the end of her first year. She goes to university. In the second year she develops a serious attraction to a classmate who she has bonded with. They date for a few years but split up when he moves away. By this point she's got to know her boss really well. He's older wiser and very attractive to her. They get together and get married. They remain married for 40 years. This woman would never realise she was demisexual as she never had a fallow period where she notice her physical attraction was only something that latently developed. She would just put this down to being in love with one man at one time and not click that there was anything out of the ordinary. She (wrongly) assumes she is oridinarily heterosexual as she's never had the opportunity to realise otherwise .
Woman is demisexual. Attends an all girls school, knows no men and doesn't bond with anyone. Goes to university, does a female dominated course and lives in an all female halls of residence. Doesn't bond emotionally with any men. Leaves university. Moves into working world where most of her colleagues are women. The ones that are men are married and avoid becoming overly close emotionally to their female colleagues. She tries internet dating but feels no attraction for any man on a first, second or third date. She assumes she is asexual as she's never had the opportunity to realise otherwise.
